[oe] libtool relink problem on libsanitizer in gcc-runtime_4.9.bbappend

[Lewis, Nick]

Until recently we have added libmudflap support via gcc-runtime_4.8.bbappend. Libmudflap is no longer supported in gcc 4.9 and Libsanitizer is the recommended replacement. I have changed the recipe to produce libsanitizer instead of libmudflap but I am getting a QA error involving libtool relink with –L/usr/lib.

I am unable to establish the cause of the problem. Could someone with libtool expertise please help me


$ cat gcc-runtime_4.9.bbappend
# Addition of Asan address sanitizer (previously Mudflap)
PRINC := "${@int(PRINC) + 1}"

# enable-libmudflap and disable-libmudflap options no longer supported
EXTRA_OECONF_BASE := "${@oe_filter_out('--disable-libmudflap', '${EXTRA_OECONF_BASE}', d)}"

RUNTIMETARGET += "libsanitizer"
PACKAGES += "libasan libasan-dev libasan-staticdev libasan-preinit libubsan libubsan-dev libubsan-staticdev"

FILES_libasan = "${libdir}/libasan*.so.*"
FILES_libasan-dev = "\
  ${libdir}/libsanitizer.spec \
  ${libdir}/libasan*.so \
  ${libdir}/libasan.la"
FILES_libasan-staticdev = "\
  ${libdir}/libasan.a"
FILES_libasan-preinit = "\
  ${libdir}/libasan_preinit.o"

FILES_libubsan = "${libdir}/libubsan*.so.*"
FILES_libubsan-dev = "\
  ${libdir}/libsanitizer.spec \
  ${libdir}/libubsan*.so \
  ${libdir}/libubsan.la"
FILES_libubsan-staticdev = "\
